Which expression represents the volume of the cone that is times the volume of the pyramid that it fits inside? (2r2h) (4r2h)

Answers

The expression represents the volume of the cone that is times the volume of the pyramid that it fits inside is Pi/4(4r²/3).

We have given that the expression represents the volume of the cone

that is times the volume of the pyramid that it fits inside

(2r^2h) (4r^2h)

What is the formula for the volume of the cone?

The formula for the volume of a cone is ⅓ r^2h cubic units.

where r is the radius of the circular base and h is the height of the cone.

Therefore from the given we get the volume of a pyramid is Pi/4(4r²/3).

In a study to determine the relationship between self esteem and eating, subjects had been randomly divided into two groups. One group of subjects were individually told something intended to boost their self esteem while in the other group subjects were individually told something intended to lower their self esteem. Each subject was then individually led into a room alone and asked to count the number of chocolate chip cookies in a very large container and told they could eat as many as they liked while conducting their count. Researchers then counted the number of cookies eaten by subjects in each group. Which of the following statements is true regarding this study? Check all that apply.

This study is an observational study.

This study is blind.

This study is an experimental study.

The treatment was the number of cookies eaten.

300 children 3/5 are boys how many are girls

Answers

So,

There are 300 children.

One-fifth of 300 is 60 (60 times 5 = 30).

(Five-fifths minus the boys) of the children are girls.

Multiply 60 by 2.
60 * 2 = 120

There are 120 girls.
Well if you divid 300 and 5 you get 60. So for every 1/5 is 60. So if you do 60 times 3 equals 120. So then you subtract 300 minus 120 and get 280. So there are 280 boy and 120 girl.

Arleen has a gift card for a local lawn and garden store. She uses the gift card to rent a tiller for 4 days. It cost $35 per day to rent the tiller. She also buys a rake for $9. A. Find the change to the value on the gift card. (Question #1)

B. The original amount on the gift card was $200. Does Arleen have enough to buy a Wheelbarrow for $50? (Question #2)

Answers

Answer:

Step-by-step explanation:

Arleen has a gift card of the amount = $200

The total cost to rent the tiller for 4 days and a rake for $9

= ($35 × 4) + $9

= 140 + 9 = $149

A. Now the balance on the gift card = $200 - $149

                                                            = $51

B. Arleen have $51 in her gift card so she has enough to buy a wheelbarrow for $50.00.

                                                                   

35 • 4 = 140 + 9 =149 for rent and rake
200 - 149 = 51 left on gift card. Yes she has enough to buy the wheelbarrow.

Which of the following equations have graphs that are parallel to the graph of the equation y=-3/2x+8? I. 3x + 2y = 10
II. 2x − 3y = 9
III. 6x + 4y = 28
IV. 3x − 2y = 8

 I and III only
 II and III only
 IV only
 III only

Answers

Parallel lines will have the same slope, but different y int
y = -3/2x + 8....slope = -3/2....y int = 8

(I) 3x + 2y = 10
    2y = -3x + 10
    y = -3/2x + 5....slope = -3/2, y int = 5....this IS parallel

(II) 2x - 3y = 9
     -3y = -2x + 9
     y = 2/3x - 3...slope = 2/3, y int = -3....is not parallel

(III) 6x + 4y = 28
       4y = -6x + 28
       y = -3/2x + 7...slope = -3/2, y int = 7....this IS parallel

(IV) 3x - 2y = 8
      -2y = -3x + 8
      y = 3/2x - 4...slope = 3/2...y int = -4...this is not parallel

solution is : I and III
